Yes, I think the thing you're looking for was written by David Biesack (
[EMAIL PROTECTED]). I am not aware of it ever having been packaged into
any sort of official package, but I do have the following in my .emacs:
;; Make cursor stay in the same column when scrolling. Thanks to

(defvar default-column nil
"The column to track in functions registered with `track-column'.
This variable is buffer local")

which are advised by `track-column'"
(if (memq last-command default-column-tracking-functions)
default-column
(setq default-column (current-column))))
(defmacro track-column(function)
"Advise FUNCTION to keep track of the default column.

I had a catastrophic machine crash and am trying to rebuild my .el files.
One I can't seem to locate was a little function that somehow
calculated or remembered where your cursor was on a page, so no matter
where you were, you could ctrl-v, m-v as much as you wanted, and the
cursor would always land on the same place on a given page.*
Does anyone know what this is called and/or where to find it?
* The effect I'm trying to avoid can easily be demonstrated by opening
an existing file longer than a screen/page long, going to the top of
the file, Ctrl-v, then M-v. The cursor is on the last line of the
screen, not the first line where it started.
